- oes every moving body posses both kinetic energy and momentum? Explain.A light object and a heavy object have the same kineticenergy. Which has the greater momentum? Explain1. You want to drive cart A, initially at rest, through a piece of paper by launching cart B against it. Both carts have the same mass, and you've determined that the larger the kinetic energy of an object, the more easily it goes through a piece of paper. One side of cart B is equipped with velcro pads so that it sticks to cart A; the other side is smooth and collides elastically. Which side of cart B do you use? Explain briefly.

- In Chapter 5, rocket propulsion was explained in terms of Newton’s third law. That is, the force that propels a rocket is from the exhaust gases pushing against the rocket, the reaction to the force the rocket exerts on the exhaust gases. Explain rocket propulsion in terms of momentum conservation.. A condition of the law of conservation of momentum is that no external forces are at play. Look at each of the following situations and determine if the law applies or does not apply. Law does apply. Law does not apply. ______ A bullet strikes a wooden block causing the block to accelerate from rest. ______ Two cars collide on a dirt road where the force of friction is high. ______ A coin sliding on a table experiences a frictional force. ______ Two kinetic carts collide on a frictionless surface.Take two different balls that can bounce (a tennis ball and a basketball combination works great) and stack the lighter ball on top of the heavier one. Release them simultaneously and let them hit the floor stacked. What happens? Pick the correct answer from the following options. Options: A) The two balls hit the ground and bounce upwards, with the heavier ball bouncing significantly higher than where it was released from. B) The two balls hit the ground and bounce upwards, with the lighter ball bouncing significantly higher than where it was released from. C) The two balls hit the ground and bounce upwards, neither ball reaching as high as it started from. D) The two balls hit the ground and bounce upwards, coming to rest pretty close to their starting positions.
- In a circus act, a 55.5 kg clown with 2.5 m/s horizontal velocity jumps into the air and is caught by a 72.5 kg clown who was initially at rest. The clown is sitting on a sheet of ice, and moves off at some new velocity, after the two clowns are stuck together. How much kinetic energy is lost during this process? Options for answers: 98.2 J 348.6 J 18.9 J 0 JUsing the principle of momentum conservation, explain what happens when a moving billiard ball collides with a stationary ball (cue ball hitting the eight ball)A curiosidade child stands on the top of a 670 m Skyscraper and Drops a coin from the top of the building.

- What is the relationship between saying conserved quantity and inelastic collision of two objects, as if the latter circumscribes the result, conserved quantity, if at all? Momentum, kinetic energy, neither, both. I don’t understand the relevant concepts.A baseball pitcher’s first pitch is a fastball, moving at high speed. The pitcher’s second pitch—with the same ball—is a changeup, moving more slowly. Which pitch is harder for the catcher to stop? Explain your answer in terms of momentum.A blob of clay and a tennis ball are thrown at a partially open door in order to try to close it. Both have the same mass. The blob of clay sticks to the door while the tennis ball bounces off. Which one will be more likely to close the door or will they both close the door by the same amount?
